The TS30042-M033QFNR Switching Regulator can be used in any application that requires a non-Isolation DC/DC switching regulator. This device is designed to convert a single-voltage input into a single output voltage. It is also ideal for applications that require a wide range of input/output voltages (up to 36V/75V), enabling the use of single- and multi-channel systems. The device is capable of providing outputs up to 1.5 A. The TS30042-M033QFNR is suitable for use in a variety of applications, such as automotive, industrial, lighting, and medical.

The TS30042-M033QFNR features a pulse width modulation (PWM) controller with selectable operating frequency, a high-side and low-side driver, and a built-in thermal regulation circuit. This DC/DC regulator operates with very high efficiency over a wide range of input/output, enabling it to be used for both multiple-channel and single-channel buck-boost applications. Additionally, it features low cost, small form factor, and a high temperature operating range of -40°C to +85°C.

The TS30042-M033QFNR working principle is simple. It is based on the buck-boost topology, where an input voltage is converted into an output voltage with different amplitudes, either boosting (increasing) or bucking (decreasing) the output voltage. The PWM controller contains an internal voltage reference, a frequency compensation loop, and circuitry to control the cycle-by-cycle current limit and shutoff when the input voltage drops below a certain level. The current limit feature offers simple yet effective protection from overcurrent faults. The transistor drivers included in theTS30042-M033QFNR are used to switch the supply voltage between the high-side and the low-side transistors in the PWM controller.

In addition, the TS30042-M033QFNR offers excellent protections against overload conditions. The pre-bias start up feature ensures that the device will start under any conditions. The open-drain output signal from the device also provides enhanced fault protection, allowing for local fault diagnosis. The device also includes a lossless current-limit detection circuitry that provides a warning signal to the system when the current limit is exceeded. This feature offers improved system reliability and protection against overcurrent faults.

The TS30042-M033QFNR is designed to work in a wide range of temperature and environmental conditions. The device is rated to operate from -40°C to +85°C. It also has a wide input voltage range, up to 36V. The switching frequency is adjustable from 50 kHz to 250 kHz. The device also features an adjustable slope compensation and output current sense circuitry, which further enhance its flexibility and efficiency.

In conclusion, the TS30042-M033QFNR is a highly efficient and cost-effective DC/DC switching regulator ideal for a variety of applications. Its adjustable output and input voltage limits, wide operating temperature range, wide input voltage range, and adjustable switching frequency make it highly suitable for applications that require a non-isolated power supply solution. Additionally, its protection features make it very reliable and provide enhanced system safety.
